Embodiment 1

[0050] see figure 1 As shown, the embodiment of the present invention provides a kind of ISDN user access system of VoIP gateway, and it is used for the ISDN user of VoIP gateway to realize user access softswitch platform when calling or being called, including service communication module, ISDN protocol module, Protocol conversion module, H.248 protocol module and softswitch platform, in which:

[0051] The service communication module is used to establish a connection with ISDN users, and is also used to send the messages extracted from the VoIP gateway to the ISDN protocol module; ISDN users include primary rate interface PRI or basic rate interface BRI users.

[0052] When the ISDN protocol module is used for ISDN users to call, after establishing a call with the ISDN user through the business communication module, the call control information is extracted from the VoIP gateway through the business communication module and sent to the protocol conversion module, and the H....

Embodiment 2

[0061] see figure 1 As shown, the embodiment of the present invention also discloses an ISDN user access method using a VoIP gateway ISDN user access system of the VoIP gateway, including:

[0062] 1. When an ISDN user makes a call, see figure 2 as shown,

[0063] A1, when an ISDN user calls, the business communication module establishes a connection with the ISDN user;

[0064] A2. After the ISDN protocol module establishes a call with the ISDN user through the service communication module, it extracts the call control information from the VoIP gateway through the service communication module and sends it to the protocol conversion module;

[0065] A3, the protocol conversion module receives the call control information from the ISDN protocol module, and converts the ISDN protocol call event into the H.248 protocol call event according to the preset number conversion rule, and converts the calling and called phone numbers in the call control information into H.248 endpoin...

Embodiment 3

[0085] Embodiment 3: For the implementation process of the VoIP gateway power-on and start-up process, see Image 6 Shown:

[0086] Step 1: Power on the VoIP gateway, first initialize the peripheral modules, including the initialization of the switching driver, device management, configuration management module, and voice service master-slave communication module, and complete the initialization of the data structure and tasks of each module.

[0087] Step 2: After the initialization of each module of the VoIP gateway is completed, configure each module to take effect.

[0088] Step 3: Call the H.248 voice initialization interface to initialize the H.248 protocol, load the voice module, and initialize the voice data structure, voice protocol stack, and voice tasks.

[0089] Step 4: Call the initialization interface of the protocol conversion module to complete the initialization of the call process mapping module under the H.248 protocol and the ISDN protocol.

[0090] Step ...

Abstract

The invention discloses an ISDN access system of a VoIP gateway, related to the VoIP gateway access technology. The ISDN access system of the VoIP gateway comprises a business communication module, an ISDN protocol module, a protocol conversion module and an H.248 protocol module. According to the invention, the ISDN protocol module and the protocol conversion module are added to the existing VoIP gateway, and part functions of the H.248 protocol module are modified; the ISDN protocol module connects ISDN users through the business communication module; the protocol conversion module realizes mutual mapping between the ISDN user calling number / called number and the H.248 endpoint; when the interactive notification call between the H.248 protocol module and the ISDN protocol module begins, the ISDN protocol module does not directly interact information with the soft switching platform, and the soft switching platform only perceives the information interaction with the H.248 protocol module, therefore, the mutual mapping between the ISDN users accessed to the VoIP gateway and the H.248 is realized, and the problem that the ISDN users can not use the H.248 network which is connected to NGN is solved.

Description

technical field [0001] The invention relates to the technical field of VoIP gateway access, in particular to a VoIP gateway ISDN user access method and system. Background technique [0002] NGN is the abbreviation of "Next Generation Network (Next Generation Network)" or "New Generation Network (NewGeneration Network)". NGN is based on VoIP gateway and soft switch as the core, can provide voice, video, data and other multimedia integrated services, adopts an open and standard system structure, and can provide a next-generation network with rich services. [0003] Existing switches and access network devices based on V5 interfaces provide a large number of ISDN (Integrated Services Digital Network, Integrated Services Digital Network) interfaces, and many commercial users and user-level switches also use ISDN interfaces, while the existing VoIP (Voice over Internet Protocol (IP telephony) gateway usually only supports NGN (Next Generation Network, next generation network) vo...
